Ive got a black 2009 2LT with the 17" aluminum wheels and my birthday is coming up and i want to get some wheels from my parents..

I already know i want the MSR 045 all black but i have no idea about the size/offset or which tire to get..

Will my stock tires fit these wheels and what size tire and offset do i need? Ive searched through here but most people are putting them on their SS and im not sure about mine

Thanks for the help guys, its much appreciated, here is a picture of my car:

 

They put those rims on LT's now from the factory? cool.

 

Yeah if you get the sport package
